* draw: implement TGSI_PROPERTY_VS_WINDOW_SPACE_POSITIONMarek Olšák2014-12-091-0/+2
| | | | | | | Required by Nine. Tested with util_run_tests. It's added to softpipe, llvmpipe, and r300g/swtcl. Tested-by: David Heidelberg <david@ixit.cz>
* draw: fixes for vertex shaders outputting layer or viewport indexRoland Scheidegger2014-11-191-1/+3
| | | | | | | | | | Mostly add a couple cases so we don't just check gs for this. There's only one gotcha, the built-in vp transform in the llvm vs can't handle it (this would be fixable though non-trivial due to vp index being non-constant for the SoA outputs, but we don't use it if there's a gs neither - the whole clip/vp transform integration there is suboptimal).

* draw: do not use draw_get_option_use_llvm() inside draw execution pathsRoland Scheidegger2014-05-081-2/+2
| | | | | | | | | | | | | | 1c73e919a4b4dd79166d0633075990056f27fd28 made it possible to not allocate the tgsi machine if llvm was used. However, draw_get_option_use_llvm() is not reliable after draw context creation, since drivers can explicitly request a non-llvm draw context even if draw_get_option_use_llvm() would return true (and softpipe does just that) which leads to crashes. Thus use draw->llvm to determine if we're using llvm or not instead (and make draw->llvm available even if HAVE_LLVM is false so we don't have to put even more ifdefs).

* draw/llvm: reduce memory usageZack Rusin2014-04-241-4/+7
| | | | | | | | | | Lets make draw_get_option_use_llvm function available unconditionally and use it to avoid useless allocations when LLVM paths are active. TGSI machine is never used when we're using LLVM. Signed-off-by: Zack Rusin <zackr@vmware.com> Reviewed-by: Roland Scheidegger <sroland@vmware.com> Reviewed-by: José Fonseca <jfonseca@vmware.com>

* gallium/draw: add limits to the clip and cull distancesZack Rusin2013-06-131-5/+5
| | | | | | | | | | | There are strict limits on those registers. Define the maximums and use them instead of magic numbers. Also allows us to add some extra sanity checks. Suggested by Brian.

* draw/llvmpipe: allow independent so attachments to the vsZack Rusin2013-04-031-0/+13
| | | | | | | | | | | | | | When geometry shaders are present, one needs to be able to create an empty geometry shader with stream output that needs to be resolved later and attached to the currently bound vertex shader. Lets add support for it to llvmpipe and draw. draw allows attaching independent stream output info to any vertex shader and llvmpipe resolves at draw time which vertex shader the given empty geometry shader should be linked to.

* draw/llvmpipe: fix transform feedback position + enable other extensionsDave Airlie2012-12-141-0/+1
| | | | | | | | | | | | | | | | This builds on the previous draw/softpipe patch. So llvmpipe does streamout calls after clip/viewport stages, but we have the pre-clip position stored for later use, so when we are doing transform feedback, and its the position vertex grab the vertex from the stored pre clip position. The perfect fix is too probably add a codegen transform feedback stage in between shader and clip stages, but this is good enough for now.

* draw/softpipe: add clip vertex support. (v2)Dave Airlie2012-01-111-0/+9
| | | | | | | | | | | | | | | | softpipe always clipped using the position vector, however for unclipped vertices it stored the position in window coordinates, however when position and clipping are separated, we need to store the clip-space position and the clip-space vertex clip, so we can interpolate both separately. This means we have to take the clip space position and store it to use later. This allows softpipe to pass all the clip-vertex piglit tests. v2: fix llvm draw regression, the structure being passed into llvm needed updating, remove some hardcoded ints that should have been enums while there.
